Possibly one of the most convienient words I've come across, it kills of un-wanted conversation very effectively without offending someone.

Indeed answers any closed question, a sarcastic remark or general remark you really don't care to comment on. In the case of open questions replying "indeed" lets someone know that you really don't give a flying pig's ass and can express surprise, skepticism, or irony.

a word used to make even the most innatentive moron sound borderline brilliant. The use of the word indeed can speak volumes of unquestioned smarts, and can suggest that the user has a great, expansive vocabulary.

Be warned, the use of indeed may cause some people to feel uncomfortable and less superior in the users presence, intimidated by their free usage of the word.
